1 Claim.

This invention relates to a dispensing cap for collapsible tubes.

An object of the invention is to provide a cap for a collapsible tube having a delivery valve mounted therein which is forced outwardly to open position by pressure on the tube, and is manually pushed inwardly to closed position.

Another object of this invention is to provide a valved cap for collapsible tubes which is of simple construction and can be used with various kinds of paste material.

With the above and other objects in View, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawing:

Figure l is a plan view partly broken away of the top of a collapsible tube having a dispensing cap, constructed according to an embodiment of this invention, mounted therein.

Figure 2 is an enlarged sectional View taken on line 22 of Figure 1.

Figure 3 is a sectional view taken on the line 33 of Figure 2.

Figure 4 is a detail side elevation of the valve element.

Figure 5 is a sectional view taken on the line 53-55 of Figure 2.

Referring to the drawing, the numeral it designates generally, a conventional collapsible tube which is provided with a neck I l and a cap, generally designated as i2, is threadably mounted on the neck i l or otherwise attached or a permanent part of the tube.

The cap includes a top wall is and a cylindrical side wall 95 which is formed with interior threads is engaging the external threads H3, which are formed on the neck ii. The cap I2 is provided with an opening ll which, as shown in Figure 1, is rectangular in plan and tapers inwardly forming a seat 18 for a valve member as will be hereinafter described.

A delivery valve, generally designated as I9, is loosely carried by the cap it and includes a hollow head 2! which is open at each end and which has extending inwardly therefrom a pair of shank or stem forming members 2| and 22. The shank or stem forming mebers 2i and 22 are flat and disposed in face abutting relation and each shank or stem forming member is provided at the inner end thereof with right angularly disposed lates 23 and 24, which constitute operating means whereby the valve will be moved outwardly to 2 open position when pressure is applied to the tube Ill, and the material therein is forced outwardly into the neck II. The stem or shank which is generally designated as 25 is provided with a lon itudinally extending opening 26 communicating with the right angularly disposed opening 21 which is formed in the head 20. The head 20 is also provided with a pair of laterally spaced delivery openings '28 and Z9 communicating with the port or opening 26 so that an additional quantity of material will be delivered from the head ZED. As shown, in, Figure 1, the head 20 is tapered on the opposite side thereof and when in closed position, is adapted to engage on the valve seat 18 with the top of the head 20 substantially flush with the outer surface of the top wall I l of cap l2.

In the use and operation of this device the tube H), which is of conventional construction and has positioned therein material of paste-like composition; such as, tooth paste, shaving cream, or the like, will have the cap [2 threaded on the neck I I. In order to deliver a quantity of the material from the tube ID, the latter is pressed or collapsed at any point along the length thereof, thereby placing the material in the neck H under pressure at which time the wings or operating members 23 and 24 of the valve structure will move outwardly to substantially contacting position with the inner side of the top wall M of cap l2. The material in the neck I I will then be forced outwardly through the opening 26 and this material will then be discharged through the opposite ends of the head 2!] and an additional quantity of material will also be discharged from the laterally spaced openings 28 and 29. After the desired quantity of material has been obtained, the valve 20 may be moved inwardly to closed position by manual pressure on the head 20 forcibly pushing the head 20 toward the top wall l4 until the head 20 is substantially flush with the top wall I 4. At this time the valve head 20 will be seated on valve seat I8.

I do not mean to confine myself to the exact details of construction herein disclosed but claim all variations falling within the purview of the appended claim.

What is claimed is:

A dispenser cap for collapsible tubes comprising a cap member formed with a rectangular opening and a tapered seat, and a valve member carried by said cap loosely engaging through said opening, said valve member comprising a flat strip bent upon itself and formed with a looped valve head engageable on said seat, a stem formed of face abutting portions of said strip, and a pair of oppositely extending wings carried by said stem, said stem having an opening extending lengthwise thereof and said head having an opening in communication with and disposed at right angles to said opening in said stem and open at both ends, said head having a pair of openings inwardly from the outer end thereof communicating with said stem opening, said tapered seat serving as a closure for said last mentioned openings, and the opposite end walls of said rectangular opening servingas a closure for ARTHUR LA SALLE.
